DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The following detailed description of example implementations refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.

In some cases, an Internet of Things (IoT) device, such as a category M1 (Cat-M1) device, uses a battery as a primary source of power for the IoT device. Some IoT devices use one or more power saving strategies, such as an extended discontinuous repetition (eDRX) strategy, a power saving mode (PSM) strategy, and/or the like, to extend the life of the battery. However, these strategies may limit the availability of the IoT device to send and/or receive information (e.g., by using small paging windows, increasing idle time, extending sleep time, and/or the like). In some cases, a server device or other network elements, such as a server device associated with the manufacturer of the IoT device, sends information to the IoT device, such as an upgrade image file, but the IoT device cannot receive the information because the IoT device is not reachable for a long enough period to receive the information. Further, in some cases, the server device and/or other network devices continue to try to deliver the information to the IoT device, even when the IoT device is not reachable, which can tie up and/or waste network resources. Moreover, in some cases, the server device attempts to simultaneously send the information to a plurality of IoT devices that are concentrated in a particular area at the same time, this may overwhelm the network devices dedicated to that particular area.

Some implementations described herein provide a device that divides a data structure into a plurality of data segments and incrementally sends the plurality of data segments to a reachable subset of user devices (e.g., IoT devices) of a set of user devices associated with a base station. This ensures that one or more data segments of the plurality of data segments are only sent when a user device of the subset of user devices is reachable, which allows the user device to receive the data structure a data segment at a time without overwhelming a network, or one or more network devices of the network, associated with the user device. In some implementations, the device obtains the data structure and a list of a plurality of user devices from a server device. In some implementations, the device divides the data structure into the plurality of data segments. In some implementations, the device obtains a respective location and a respective reachability of each user device of the plurality of user devices to determine a set of user devices connected to a base station. In some implementations, the device determines a communication capability of the base station to determine a subset of user devices of the set of user devices and one or more sets of data segments of the plurality of data segments. In some implementations, the device sends the one or more sets of data segments to the subset of user devices via the base station based on the respective reachability of each user device of the subset of user devices. In some implementations, a user device of the subset of user devices sends, to the device, an acknowledgment message after receiving a data segment and/or a final acknowledgment message after receiving all the plurality of data segments.

In this way, some implementations provide a device that may target a portion of the set of user devices that are associated with a base station (e.g., the subset of user devices that are reachable) to receive the one or more sets of data segments that collectively comprise the data structure. This may increase a likelihood of delivering the data structure to the portion of user devices than would occur by attempting to deliver the data structure to the entire set of user devices associated with the base station. This also reduces the load on the base station, or other network devices, associated with the set of user devices. Further, some implementations provide a device that may send information to a user device a block or segment at a time, thereby ensuring that the user device can receive the information segment-by-segment while the user device is reachable. This may increase reliability for the user device to receive critical updates, such as security patches, software upgrades, critical configuration files, and/or the like, which may ensure proper functioning of the user device and reduce a likelihood of the user device malfunctioning and/or being subjected to a hacking attempt, malware infection, and/or the like.

Moreover, some implementations provide for a user device to send acknowledgment messages to the device regarding the user device obtaining one or more data segments, which may prevent the device from resending successfully received data segments. This conserves resources (e.g., processor resources, memory resources, network resources, power resources) of the device, the user device, the base station, one or more other devices, and/or the like that would otherwise be wasted by repeatedly resending the data segments to the user device.

FIGS. 1A-1E are diagrams of one or more example implementations 100 described herein. Example implementation 100 illustrate various portions of one or more wireless telecommunications systems, such as a long term evolution (LTE) wireless telecommunications system, a 3G wireless telecommunications system, a 4G wireless telecommunications system, an LTE-Advanced (LTE-A) wireless telecommunications system, a 5G wireless telecommunications system, and/or the like.

As shown in FIG. 1A, example implementation 100 may include one or more user devices (shown as user devices 102-1 through 102-L) connected to one or more radio access networks (RANs) at one or more base stations (shown as gNB/eNBs 104-1 through 104-M), such as a gNB base station associated with a 5G telecommunications system, an eNB base station associated with an LTE telecommunications system, and/or the like. For example, a first set of user devices (e.g., one or more user devices 102-1) may be wirelessly connected with gNB/eNB 104-1 and a second set of user devices (e.g., one or more user devices 102-L) may be wirelessly connected with gNB/eNB 104-M. In some implementations, a base station may have a communication capability that includes one or more properties such as a bandwidth, a capacity (e.g., a maximum number of data connections supported by the base station), a coverage area, a frequency range, and/or the like.

As further shown in FIG. 1A, a base station of the one or more base stations may be connected to a network device (shown as AMF/MMEs 106-1 through 106-N), such as an access and mobility management function (AMF) associated with a 5G telecommunications system, a mobility management entity (MME) associated with an LTE telecommunications system, and/or the like. For example, gNB/eNB 104-1 may be connected with AMF/MME 106-1 and gNB/eNB 104-M may be connected with AMF/MME 106-N. In some implementations, the network device may communicate with a set of user devices associated with a base station, of the one or more user devices, via the base station. In some implementations, the network device may communicate with the set of user devices to determine, for each user device of the set of user devices, information concerning a location of the user device and/or information concerning a reachability of the user device. In some implementations, the information concerning the location of the user device may include a physical location of the user device (e.g., a latitude and longitude of the user device); a geographic area associated with the user device (e.g., a country associated with user device; a state associated with the user device; a region associated the user device, such as the Pacific Northwest, the East Coast, the Great Lakes region, and/or the like; an identifier of a base station (e.g. a base station identification string) associated the user device; an identifier of a network device (e.g., a network device identification string) associated with the base station and/or the user device; and/or the like. In some implementations, the information concerning the reachability of the user device may include a reachability status of the user device (e.g., whether the user device is active, awake, asleep, idle, connected, and/or the like); a reachability time of the user device (e.g., a time when the user device is reachable, how long the user device is reachable, a schedule of when the user device is reachable and/or for how long, and/or the like); and/or the like. In some implementations, the network device may store the information concerning the location of the user device and/or the information concerning the reachability of the user device.

As further shown in FIG. 1A, the network device may be connected to a network exposure device, such as an exposure function device (shown as NEF/SCEF 108) that may include one or more components for communicating with different telecommunications systems, such as a network exposure function (NEF) for a 5G telecommunications system, a service capability exposure function (SCEF) for an LTE telecommunications system, and/or the like. In some implementations, one or more network devices, such as one or more network devices that support different telecommunications systems, may be connected to the same network exposure device. For example, AMF/MME 106-1 may be connected with NEF/SCEF 108 and AMF/MME 106-N may be connected with NEF/SCEF 108. In some implementations, the network exposure device may be connected to a server device (shown as server 110), such as an application server, to facilitate communication between the one or more user devices and the server device. For example, the NEF/SCEF 108 may be connected with server 110.

As shown in FIG. 1B and by reference number 112, the server device may send a data structure, such as a software upgrade file image, a security patch, a configuration file, an update file, one or more messages, and/or the like to the network exposure device. In some implementations, the data structure may be associated with and/or comprise instructions, such as executable code (e.g., software code, machine language code, and/or the like). In some implementations, a user device may be configured to execute the instructions upon receiving the data structure. In some implementations, the server device may send, to the network exposure device, information identifying one or more user devices that are to receive the data structure. In some implementations, the information may include a list of the one or more user devices, a respective identifier associated with each user device of the one or more user devices, a respective capability of each user device of the one or more user devices, a respective type of each user device of the one or more user devices, and/or the like. For example, the server device may send the data structure and information that includes a list of the one or more user devices to the network exposure device. In some implementations, the network exposure device may identify the one or more user devices that are to receive the data structure based on the information identifying the one or more user devices. For example, the network exposure device may parse the information identifying the one or more user devices to determine the respective identifier associated with each user device of the one or more user devices.

As shown by reference number 114, the network exposure device may divide the data structure into a plurality of data segments. In some implementations, the network exposure device may divide the data structure into a plurality of data segments of a particular size. For example, the network exposure device may determine a respective reachability of each user device of the one or more user devices (e.g., as described herein in relation to FIG. 1C) and determine one or optimal data segment sizes based on a respective reachability of a user device (e.g., one or more data segment sizes that can be transmitted to the user device during a period of time that the user device is reachable). As another example, the network exposure device may determine a communication capability of a base station (e.g., as described herein in relation to FIG. 1D) and determine one or more optimal data segment sizes based on the communication capability (e.g., one or more data segment sizes that correspond to one or more message sizes used by the base station for communicating with a user device). In some implementations, the network exposure device may divide the data structure into the plurality of data segments according to the one or more optimal data segment sizes.

As shown in FIG. 1C, the network exposure device may determine a location and/or a reachability of each user device of the one or more user devices. As shown by reference numbers 116-1 to 116-N, the network exposure device may send a query regarding the one or more user devices to each network device of the one or more network devices. In some implementations, the query may include a request for information concerning a respective location and/or a respective reachability of each user device of the one or more user devices. As shown by reference numbers 118-1 to 118-N, each network device of the one or more network devices may send information concerning the respective location and/or the respective reachability of each user device associated with the network device to the network exposure device. In some implementations, the information may include, for a user device associated with a network device, a user device identifier (e.g., a device identification string); an identifier of a base station associated the user device; an identifier of the network device associated with the base station and/or the user device; information identifying a physical location of the user device; information identifying a geographic area associated with the user device; a reachability status of the user device; a reachability time of the user device; and/or the like.

As shown by reference number 120, the network exposure device may determine, based on the respective location of each user device of the one or more user devices, a set of user devices, of the one or more user devices, connected to a base station. For example, the network exposure device may determine a set of user devices 102-1 that are connected to gNB/eNB 104-1, a set of user devices 102-L that are connected to gNB/eNB 104-M, and/or the like. In some implementations, the network exposure device may determine, based on the respective location of each user device of the one or more user devices, a network device, of the one or more network devices, that is associated with the base station and the set of user devices. For example, as shown in FIG. 1C, the network exposure device may determine that AMF/MME 106-1 is associated with gNB/eNB 104-1 and the set of user devices 102-1, that AMF/MME 106-N is associated with gNB/eNB 104-M and the set of user devices 102-L, and/or the like. In this way, the network exposure device may determine which user devices are associated with a base station and/or network device.

As shown in FIG. 1D, the network exposure device may determine a communication capability of a base station associated with a set of user devices and/or a network device associated with the set of user devices. As shown by reference number 122, the network exposure device may send a query regarding the base station to the network device associated with the base station. In some implementations, the query includes a request regarding the communication capability of the base station. As shown by reference number 124, the network device may send the query to the base station. As shown by reference number 126, the base station may send information concerning the communication capability of the base station to the network device. As shown by reference number 128, the network device may send the information concerning the communication capability of the base station to the network exposure device. As shown by reference number 130, the network exposure device may process the information concerning the communication capability to determine the communication capability of the base station. While it is possible that the network exposure device communicates with a single base station via a single network device to determine a communication capability of the single base station, in practice, the network exposure device may communicate with multiple base stations via multiple network devices to determine the communication capabilities of the multiple base stations.

In some implementations, the network exposure device may determine, based on the communication capability of the base station, a subset of user devices of the set of user devices. For example, the network exposure device may determine, based on the capacity of the base station (e.g., the number of user devices that can be supported by the base station at one time), an optimal number of user devices for the base station to communicate with and determine the subset of user devices to comprise the optimal number of user devices. Additionally, or alternatively, in some implementations, the network exposure device may determine, based on the respective reachability of each user device of the user devices, the subset of user devices of the set of user devices. For example, the network exposure device may determine, based on the respective reachability of each user device of the set of user devices, a subset of user devices that are reachable during a period of time (e.g., those user devices that are reachable during a 1 hour window, a 4 hour window, a 24 hour window, and/or the like).

In some implementations, the network exposure device may determine, based on the communication capability, one or more sets of data segments of the plurality of data segments. For example, the network exposure device may determine, based on the bandwidth of the base station, an optimal number of data segments to transmit to a user device and limit the number of data segments in a set of data segments, of the one or more sets of data segments, to the optimal number of data segments.

As shown in FIG. 1E, the network exposure device may send the plurality of data segments to the subset of user devices and receive one or more acknowledgment messages from the subset of user devices. In some implementations, the network exposure device may send the plurality of data segments to the subset of user devices one data segment at time, two or more data segments at a time, one set of data segments at a time, two or more sets of data segments at a time, and/or the like.

In some implementations, the network exposure device may generate a message (e.g., a delivery message), where the message includes a data segment. In some implementations, a message may include a message header, the data segment, a data segment identifier, a total number of the plurality of data segments, a checksum concerning the data segment, and/or the like. In some implementations, the network exposure device may generate one or more messages, where each message includes a respective data segment of a set of data segments. In some implementations, the network exposure device may send the one or more messages (e.g., consecutively, one message at a time), to at least one user device of the subset of user devices. In some implementations, the network exposure device may send, based on the respective reachability of each user device of the subset of user devices, the one or more messages to the subset of user devices. For example, the network exposure device may determine, for a user device of the subset of user devices, a time of reachability of the user device and send, based on the time of reachability of the user device, the one or more messages to the user device.

As shown by reference number 132, the network exposure device may send the one or more messages to the network device. As shown by reference number 134, the network device may receive the one or more messages and may send the one or more messages to the base station. As shown by reference number 136, the base station may receive the one or more messages and may send the one or more messages to at least one user device of the subset of user devices. In some implementations, the at least one user device may receive the one or more messages. In some implementations, the at least one user device may parse the one or more messages and store the respective data segments of the one or more messages.

In some implementations, the at least one user device may generate one or more acknowledgment messages, where each acknowledgment message may correspond to a respective message of the one or more messages. In some implementations, an acknowledgment message may indicate whether the at least one user device has successfully obtained a respective data segment included in a message of the one or more messages. For example, the acknowledgment message may indicate that the at least one user device received a data segment included in a message and that the at least one user device verified the integrity of the data segment using the checksum included in the message. As another example, the acknowledgement message may indicate that the at least one device received a message, but that the at least one user device determined that the message did not include a data segment, the at least one user device was unable to save the data segment, and/or the data segment was incomplete, corrupted, and/or the like. In some implementations, the acknowledgement message may include a message header, a data segment identifier, a status indicator concerning a data segment (e.g., whether the user device has successfully obtained the data segment included in a message), a status explanation concerning the data segment (e.g., additional information concerning why the user device successfully obtained or unsuccessfully obtained the data segment); and/or the like.

As shown by reference number 138, the at least one user device may send the one or more acknowledgment messages to the base station. As shown by reference number 140, the base station may receive the one or more acknowledgment messages and may send the one or more acknowledgment messages to the network device. As shown by reference number 142, the network device may receive the one or more acknowledgment messages and may send the one or more acknowledgment messages to the network exposure device.

As shown by reference number 144, the network exposure device may receive and process the one or more acknowledgment messages. In some implementations, the network exposure device may determine, based on the one or more acknowledgment messages, that the at least one user device has obtained the respective data segments included in the one or more messages. Accordingly, in some implementations, the network exposure device may generate one or more additional messages, where each additional message includes a respective data segment of an additional set of data segments, and send the one or more additional messages to the at least one user device in a similar manner as described herein in relation to FIG. 1E and reference numbers 132-136. In some implementations, the at least one user device may generate one or more additional acknowledgment messages, where each additional acknowledgment message corresponds to a respective additional message of the one or more additional messages, and send the one or more additional acknowledgment messages to the network exposure device in a similar manner as described herein in relation to FIG. 1E and reference numbers 138-142. In some implementations, the network exposure device may process the one or more additional acknowledgment messages to determine that the at least one user device has obtained the respective data segments included in the one or more additional messages. In this way, the network exposure device can transmit the plurality of data segments to the at least one user device, one set of data segments at a time, until the at least one user device has received all the data segments that collectively comprise the data structure.

In some implementations, the network exposure device may determine, based on the one or more acknowledgment messages, that the at least one user device has not obtained the respective data segments included in the one or more messages. Accordingly, in some implementations, the network exposure device may resend at least one message of the one or more messages to the at least one user device in a similar manner as described herein in relation to FIG. 1E and reference numbers 132-136. Additionally, or alternatively, in some implementations, the network exposure device may communicate with the base station to cause the base station, which may save the one or more messages for a period of time, to resend the at least one message of the one or more messages to the at least one user device. In some implementations, the at least one user device may generate at least one new acknowledgment message, where the at least one new acknowledgment message corresponds to the at least one message of the one or more messages, and send the at least one new acknowledgment message to the network exposure device in a similar manner as described herein in relation to FIG. 1E and reference numbers 138-142. In some implementations, the network exposure device may receive and process the at least one new acknowledgment message in a similar manner as described herein in relation to FIG. 2E and reference number 144. In this way, the network exposure device ensures that all data segments that are part of a set of data segments are transmitted to the at least one user device without having to resend messages that include data segments already successfully obtained by the at least one user device. This can conserve resources (e.g., processor resources, memory resources, network resources, power resources) of the network exposure device, the network device, the base station, and/or the user device that would otherwise be wasted by repeatedly resending each message of the one or more messages to the at least one user device.

In some implementations, after receiving all the data segments of the plurality of data segments, the at least one user device may send a final acknowledgment message to the network exposure device. In some implementations, the final acknowledgment message may indicate that the at least one user device successfully obtained all data segments that collectively comprise the data structure. In some implementations, at least one user device may send the final acknowledgment message to the base station, which may receive and send the final acknowledgment message to the network device. In some implementations, the network device may receive the final acknowledgment message and send the final acknowledgment message to the network exposure device. In some implementations, the network exposure device may receive and send the final acknowledgment message to the server device. In some implementations, the network exposure device may send information concerning a data structure receipt status of the at least one user device to the server device, a data structure receipt status of the subset of user devices, a data structure receipt status of the set of user devices, and/or the like to the server device.

In some implementations, after receiving all the data segments of the plurality of data segments, the at least one user device may reassemble the data structure. Accordingly, in some implementations, the at least one user device may execute the instructions associated with the data structure. In some implementations, the at least one user device may send an update acknowledgment message to the network exposure device. In some implementations, the update acknowledgement message may indicate whether the user device successfully processed the data structure (e.g. executed the instructions) to update the user device. In some implementations, at least one user device may send the update acknowledgment message to the base station, which may receive and send the update acknowledgment message to the network device. In some Implementations, the network device may receive the update acknowledgment message and send the update acknowledgment message to the network exposure device. In some implementations, the network exposure device may receive and send the update acknowledgment message to the server device. In some implementations, the network exposure device may send information concerning an update status of the at least one user device to the server device, an update status of the subset of user devices, an update status of the set of user devices, and/or the like to the server device. In this way, the network exposure facilitates updating one or more user device and notifying the server device that the one or more user devices have been updated.

As indicated above, FIGS. 1A-1E are provided merely as examples. Other examples can differ from what was described with regard to FIGS. 1A-1E. Further, the number and arrangement of devices and networks shown in FIGS. 1A-1E are provided as an example. In practice, there may be additional devices and/or networks, fewer devices and/or networks, different devices and/or networks, or differently arranged devices and/or networks than those shown in FIGS. 1A-1E. Furthermore, two or more devices shown in FIGS. 1A-1E may be implemented within a single device, or a single device shown in FIGS. 1A-1E may be implemented as multiple, distributed devices. Additionally, or alternatively, a set of devices (e.g., one or more devices) of example implementation 100 may perform one or more functions described as being performed by another set of devices of example implementation 100.

FIGS. 2A-2B are diagrams that show example information that may be stored by the network exposure device, an example message that can be transmitted from the network exposure device to a user device, and an example acknowledgment message that can be transmitted from the user device to the network exposure device. As shown in FIG. 2A, the network exposure device may store information about the one or more user devices, the one or more base stations, the one or more network devices, the plurality of data segments, and/or the like to facilitate the actions taken by the network exposure device described in FIGS. 1A-1E. As shown by reference number 202, the network exposure device may maintain information concerning a status of delivering a data structure to a subset of user devices (e.g., reachable user devices associated with a base station). For example, the network exposure device may maintain a table that includes a “job” identifier (e.g., a job to deliver a data structure to a subset of user devices), a “# of segments identifier” (e.g., a number of data segments that collectively comprise a data structure), a “% of UE” identifier (e.g., a percentage of user devices, of a set of user devices associated with a base station, that comprise the subset of user devices), a “progress” identifier (e.g., an indication of how many data segments have been delivered to the subset of user devices), and/or the like.

As shown by reference number 204, the network exposure device may maintain information concerning a base station. For example, the network exposure device may maintain a table that includes a “Cell-ID” identifier (e.g., an identifier of a base station), a “# of devices” identifier (e.g., a number of user devices in a set of user devices connected to the base station), a “Serving AMF/MME” identifier (e.g., an identifier of a network device associated with the base station), a “Device IDs” identifier (e.g., an identifier of each user device of the set of user devices associated with the base station), and/or the like.

As shown by reference number 206, the network exposure device may maintain information concerning a reachability of a set of user devices associated with a base station. For example, the network exposure device may maintain a table that includes a “Cell-ID” identifier (e.g., an identifier of a base station), a “Reachable” identifier (e.g., a number of user devices in a set of user devices connected to the base station that are reachable (e.g., a number of user devices in a subset of user devices)), an “Availability Time” identifier (e.g., a time or times when the reachable user devices are reachable), a “Serving AMF/MME” identifier (e.g., an identifier of a network device associated with the base station), an “Image Segment list refs” identifier (e.g., an identifier for each data segment of a plurality of data segments that comprise a data structure), a “Current seg status” identifier (e.g., a status of whether the subset of user devices have received all the data segments of the plurality of data segments), a “Final status” identifier (e.g., a status of whether the network exposure device is still attempting to send the plurality of data segments to the subset of user devices), and/or the like.

As shown in FIG. 2B, the network exposure device may send an example message and a user device (e.g., a user device of a subset of user devices) may send an example acknowledgement message. As shown by reference number 208, the example message may include non-IP data delivery (NIDD) information, such as a “NIDD header,” which may include information identifying the network exposure device, and a “NIDD Payload” field. In some implementations, the “NIDD Payload” field may include a “Type=IUG” field, which indicates that the message is associated with an upgrade image file, a “Length field,” which indicates a length of the message in bits and/or bytes, and an “IUG Payload” field. In some implementations, the “IUG Payload” field may include a “Total Segment” field, which indicates a total number of a plurality of data segments that comprise a data structure, a “Current Segment” field, which identifies a data segment, a “Checksum” field, which includes a checksum value to validate the data segment, and an “Image Segment Payload” field, which includes the data segment.

As shown by reference number 210, the example acknowledgment message may include NIDD information, such as a “NIDD header,” which may include information identifying the user device, and a “NIDD Payload” field. In some implementations, the “NIDD Payload” field may include a “Type=IUG-ACK” field, which indicates that the acknowledgement message is an acknowledgment message associated with an upgrade image file, a “Length field,” which indicates a length of the acknowledgement message in bits and/or bytes, and an “IUG-ACK Payload” field. In some implementations, the “IUG-ACK Payload” field may include a “Total Segment” field, which indicates a total number of a plurality of data segments that comprise a data structure, a “Current Segment” field, which identifies a data segment, a “Status” field, which indicates whether the user device successfully obtained the data segment included in a message, and a “Reason code” field, which includes additional information concerning why the user device successfully obtained or unsuccessfully obtained the data segment.
